SPECIFICATION forming part of Letters Patent No. 664,069, dated December 18, 1900. Application led July 1, 1899. Serial No. 722,544. (No model.)

To all whom t may concern.-

Be it known that I, JOHN T. WALKER, a citizen of the United States, residing at Norman, in the county of Cleveland and Territory of Oklahoma, have invented certain new and useful Improvements in Pumps, of which the following is a specification.

My invention is an improved water-pump.

The particular advantage claimed by me for this pump is that it throws a continuous stream of water to any height within the power of the pump. The pump has six ballvalves and two cylinders, t'wo valves in each of the cylinders. These cylinders terminate in two tapering or cone-shaped pipes, the upper ends gradually tapering int-o a lsingle pipe. These two upper cone-shaped parts 5 and 6 have each a ball-valve.

The pump may be operated either by crank or lever power.

The operating attachment is adjustable and may be lowered or raised to suit the convenience of the operator or conditions.

This pump may be used under ground in mines and other like places, in which case the top or upper end of the pump can be above ground. By attaching a hose to the pump it may be used to force water to a great height.

My invention is described as follows:

Figure 1 is an elevation of my invention. Fig. 2 is a view showing one ofthe cylinders and the pipes in section, the head and framework for operating the beam being shown in perspective.

l represents the head of the pump. The head of the pump is hollow and is provided with a cap 2, which is screwed on. This cap may be screwed off, and rubber tubing or any kind of piping may be attached to the threaded neck. 3 is the no'zzle, which may also be provided with a cap to iit closely lthereon when t-he water is intended to be sentV out through the neck of the head.

Extending from the head downwardly to any desired distance is a pipe 4. This pipe 4 has attached to its lower end two diverging cone-shaped pipes 5 and 6. To the lower ends of these two diverging cone shaped pipes are secured two lower cylinders 7 and 8, respectively. Thelower ends of these cylinders 7 and 8 are closed by heads 10, each being provided with a valve-seat 11, and in each one of these valve-seats rests a ballvalve 12, and to the lower ends of each of these heads 10 are secured loops 9 to prevent -large pieces of foreign matter from entering into the pump. In each one of these cylinders 7 and 8 and near their lower ends is situated a moving cup-piston 13. Said cup-pistons are each provided with a ball-valve 15, and over the top of each cup-piston is a strip 16 to keep the ball-valve from working out. In each of the diverging cone-shaped pipes 5 and 6 is a.

rod 17, and under these rods is situated a hall-valve 18. Secured to each of the cuppistons 13 is a rod 19, extending upwardly and through an opening 2O in the upper ends of the said cylinders 7 and 8. These rods extend through the platform or disk 21, which is attached to the pipe 4 at a point which is supposed to be above the ground.

Secured to the pipe 4 above the disk 21 is the operating mechanism, which is constructed substantially as follows: Two bands 22, one above the other, are brought around the pipe 4 and secured thereto by tightening the bands by means of bolts and nuts or by any other known mechanical device. These bands 22 are each provided with arms 23. These arms are provided with perforations 24, and between these arms and running vertically .are secured two uprights 25, making a rectangular framework, and to the upper end of this rectangular framework is secured a crossbeam 26, which acts as a bearing for gearingwheels. This cross beam 26 is properly braced by braces 27, and to this beam 26 are journaled three cog-wheels 28, 29, and 30. Underneath this beam 26 and some little distance from the same is hinged a walking-beam 3l. This walking-beam is provided with bolts or bearings 32 and 33. To the axle of the center cog-wheel 29 is secured a crank-handle 34, which is used to operate said wheel. Near the periphery of each Wheel is a pin 35, and to each or' these pins is pivoted the upper'end of a rod 36, the lower ends of which are pivoted to the bearings 32 and 33, and to these bearings 32 and 33 are pivoted the Lipper ends of the rods 19.

The operation is as follows: The three wheels 28, 29, and 30 mesh with each other. The operator takes hold of the crank-handle IOO ` with valves and valve-seats and cup-pistons,

substantiallyas described; adjustable bands, encircling the main pipe, and having arms extending therefrom; uprights, secured to said arms; a cross-beam secured to said uprights; a walking-beam hinged between said uprights; cog-wheels, journaled to said crossbeam and meshing with each other; two pitmen, the upper end of one pivoted to one outer cog-wheel, its lower end to the corresponding end of the walking-beam, the upper end of.

the other arm, pivoted to the other outer cogwheel, its lower end to the corresponding end of said walking-beam; two rods, their upper ends pivoted, one to each end of said walking-beam, their lower ends extending into the cylinders and secured, one to each of said cup-pistons, said cog-wheels adapted to be operated bya crank-handle or other suitable means, and thereby operate said Walkingbeam, said rods and said cup-pistons, substantially as shown and described and for the purposes set forth.

In testimony whereof I aix my signature in presence of two witnesses.
